Weekend track work between South Hayward and Union City

Last Updated On Jul. 31, 2019

This schedule has been updated as of August 11, 2022. 

A large construction project is now underway in southern Alameda County. Crews are replacing critical trackway components between the South Hayward and Union City BART stations as well as advancing preliminary work to create a new storage facility at the Hayward Maintenance Complex for hundreds of Fleet of the Future cars. 

Crews made significant progress on upgrading the BART trackway between South Hayward and Union City in 2021. Accomplishments of the BART work team include:

  • Laid 3,000 feet of new rail
  • Replaced outdated wooden rail ties with 600 more reliable concrete versions
  • Placed 800 tons of new rock ballast to improve track stability
  • Installed 1,700 feet of electric third rail to enhance power reliability for trains

Upcoming construction will build off last year’s successfully completed work. The project will require a series of weekend track shutdowns between South Hayward and Union City. On those weekends, free buses instead of trains will carry passengers between those two stations. There will be no train service between South Hayward and Union City on the following weekends:

  • August 13-14
  • September 3-5 (Labor Day weekend)
  • September 10-11

On all these weekends free buses will replace trains and riders should plan to add 20-25 minutes to their trips. Bicycles are welcome on the bus bridge. AC Transit buses typically have a capacity of three bicycles per bus. The work will require some late-night train cancellations on shutdown weekends.

On Saturdays, Sundays, and holidays impacted by shutdowns the last train of the night that normally leaves Berryessa Station at 11:48 pm will be cancelled. Passengers traveling northbound must catch the earlier train at 11:38 pm on Saturdays and 11:20 pm on Sundays. Also on Saturdays, Sundays and Holidays, the Green Line (Berryessa/North San Jose-Daly City) will not operate between Union City and Berryessa. The Orange Line (Berryessa/North San Jose-Richmond) will operate every 30 minutes, and arrival times may differ from the printed schedule. Please check the BART Trip Planner to see the scheduled departure times between Berryessa and Union City on these weekends.

BART is targeting stretches of trackway in the system that are in the greatest need of replacement and prioritizing work on those sections. This critical work will replace nearly 50-year-old track infrastructure. Many of these aging track components have been in operation since the beginning of BART service in 1972 and have outlived their design lives. Funding for the track replacement work is coming from voter-approved Measure RR.  Funding for the new rail car storage facility is provided in part by a $1.17 billion grant from the Federal Transit Administration. The storage facility is part of the Transbay Corridor Core Capacity Program, which will dramatically increase the number of trains BART can run through the Transbay Tube.

Neighbors can expect construction on or near our trackway and the operation of construction equipment with lights on nights throughout the duration of the work. Part of the project will involve the construction of a retaining wall.  The equipment used for this part of the project installs the piles for the wall by vibrating the piles into the ground. This has the potential to create significant noise at the work site.

Once complete, you can expect a decrease in the noise level from trains.  BART passengers should experience a smoother, safer, and more reliable ride.  The new rail car facility will bolster BART’s service to San Jose as well as help to ensure BART is maximizing the number of Fleet of the Future trains in operation.

Work on trackway improvements and the Hayward Maintenance Complex will continue into next year with a series of weekend track shutdowns expected between Union City and Fremont in 2023. Dates for those shutdowns have not yet been finalized.
